Answer 5

i think the answer will be the gradual warming of earths atmosphere over time

Answer 6

That's the best answer, I think @warood is right on

Answer 7

the 2nd and 3rd options are cyclical, so they reoccur (this is not a trend), random processes are also not trends

Answer 14

im not sure wat do do u think neuro?

Answer 15

i think its also true

Answer 16

@Neuronerd what u think it is?

Answer 17

I totally agree with @warood!

Answer 18

patterns are recognizable and predictable events (not necessarily cyclical or gradual)

Answer 19

is it direct?

Answer 20

i think its indirect what do you think neuro?

Answer 21

direct. First of all the logic is there (there is nitrogen in sewage) and the data confirms it by gradually declining the further away from the treatment plant

Answer 22

It would be indirect if somehow the distance would cause something else to alter the nitrogen presence

Answer 23

so its direct?

Answer 24

But that's not the case here so its direct

Answer 25

is this correct @warood?

Answer 26

the amount of pollution in the nearby pond and the number of airplanes that fly over the pond have a non related relationship what will happen to the number of airplanes that fly over the pond as the amount of pollution increases??

increase
decrease***
stay the same or responds randomly
increase then decrease in a reqular pattern

Answer 27

its kind of a misnomer to call it a 'non-related relationship' but this implies that one does not affect the other

Answer 28

i think its stay the same or responds randomly

Answer 29

I agree with @warood!

non related
cyclic
indirect***
direct

Answer 36

Hi Janice, to answer the first question about foxes and rabbits: this is an indirect relationship. Since there is no literal reaction that creates more foxes with the addition of rabbits, there is an indirect relationship as foxes prey on rabbits and are a staple in their diet. However, it is important to stress that this is indirect because one does not DIRECTLY cause the other. This is something along the lines of correlation DOES NOT equate to causation.

Answer 37

To answer your last question: this is a direct relation since the red is directly related to the amount of a certain chemical (which I am assuming is a pigment like carotene, which causes the red appearance after the chlorophyll has run dry). Please let me know if that makes sense!
